Currently running 0.18.34. I am experiencing a bug right now where if I copy/cut the contents of one chest, I cannot copy/cut the contents of another chest until I have completely emptied the first chest. So if I copy/cut a chest full of landfill and past most (but not all) of the contents to another chest, if I go to another chest full of sulfur and cut/copy it, I get no notification and when I paste to another chest, I end up moving all the landfill from the last cut/copy.
